After screen replacement in iPhone 7, the front camera won't focus/blu
I recently replaced an iphone 7 screen with no problem other than the initial adhesive difficulties getting started. Once everything was complete, I discovered the front facing camera is very blurry. It's impossible to even make out what the camera is looking at. The rear camera operates perfectly.
I took the phone apart again to clean the camera lens and the glass with no avail. Why is this happening and how can I fix it?
